Lipids

Cholesterol: Cholesterol is a white, waxy substance found naturally throughout the body. It is a fatty substance that your body needs to make cells, but too much can clog the arteries. Cholesterol is produced by the body as well as taken in through the food we eat.

Lipoproteins are formed between cholesterol and protein. There are several forms of lipoprotein such as:

Low Density Lipoproteins (LDL) which are called the bad cholesterol. It transports cholesterol from the liver to the cells in the body. It increases the development of coronary artery disease by sticking to the walls of the arteries.

High Density Lipoproteins (HDL) which are called the good cholesterol. It removes cholesterol from the cells and carries it back to the liver to be taken out to the body.
